Definitions

  • the invention relates to a control device for controlling a fluid flow according to the specified in the preamble of claim 1.
  • a dynamic seal is used to seal bushings, for example in the valve housing, by means of which a translational or rotational movement is introduced into the valve housing by means of a shaft. With the help of this shaft, the valve body is moved by different positions of the valve body, the desired throttle effect is achieved. Dynamic seals are subject to wear and other mechanisms that may leak process fluid into the surrounding atmosphere.
  • the invention is based on the object, a control device for controlling a fluid flow according to the type specified in the preamble of claim 1 while avoiding the disadvantages mentioned in such a way that the risk of leakage and thus leakage of process fluid is reduced in the surrounding atmosphere.

Furthermore, the actuating device comprises a valve body operatively engageable with the valve body and a valve rod for actuating the valve body and a device for actuating the valve rod.
  • an additional housing is fluid-tightly arranged on the main housing in such a way that the basic and additional housing forms, with the exception of the inlet and outlet, a housing which is closed on all sides, completely encapsulated, having only one circumferential seal, the valve rod being free from execution, i.e. from the housing. is arranged completely inside the closed housing.
  • the inventive design of the basic and additional housing as a closed housing and the inventive implementation-free arrangement of the valve rod in the interior of the closed housing an actuating device is provided in an advantageous manner that corresponding dynamic seals for sealing an extending into the valve housing valve rod no longer has , so that the risk of leakage due to a damaged dynamic seal is no longer possible now.
  • the device for actuating the valve rod is arranged outside the closed housing and is non-contact with the valve rod in operative connection. This has the effect that the housing has no further opening for driving the valve rod, so that the risk of leakage is additionally reduced.
  • the device for actuating the valve rod is designed such that it actuates the valve rod via a magnetic and / or electromagnetic force.
  • valve rod to an iron core or a magnet, while outside of the closed housing, a reference to the housing displaceable outer magnet is arranged.
  • a non-contact actuation of the valve rod can be initiated.
  • This embodiment of the device for actuating the valve rod is characterized in particular by its constructive simplicity and reliability.
  • the valve rod in turn has an iron core or a magnet, while outside of the closed housing, a fixedly mounted on the housing electromagnet is arranged.
  • a fixedly mounted on the housing electromagnet By changing the current flow through the electromagnet, a different force is exerted on the valve rod, via which the non-contact actuation of the valve rod is controllable.
  • the use of a permanently mounted on the housing electromagnet proves to be advantageous because a simplified structure is ensured due to the elimination of a relative movement between the outer magnet and the housing.
  • the valve body is in operative connection with a drive arranged within the closed housing, the drive being fed by means of the fluid flowing through the actuating device.
  • fluidically operated drives according to the prior art are possible as actuators, pneumatically as well as hydraulically actuated.
  • a linear drive in principle - with a suitable deformation of the movement and part-turn actuators are conceivable.
  • a fluidically actuated positioner according to the prior art is conceivable, which is housed within the closed housing in principle. The positioner would detect the position of the valve body and perform a corresponding position control.
  • FIG. 1 A possible example of such a positioner shows Fig. 1 from DE 28 47 380 A1
  • the lever 5 would have to be provided with a magnet whose applied force is controlled by an out-of-housing device as described above.
  • the inflowing fluid in the valve inlet of the actuator according to the invention would act on the input 8.
  • Input 3 would be omitted, the fluid flowing out of the nozzle 7 would be suitably transferred into the valve outlet of the actuator according to the invention.
  • the valve rod is complete and the valve body partially guided in the housing and between the valve body and valve rod, a first and a second chamber are formed, which are in fluid communication with each other via a through hole, wherein the valve body associated with the first chamber via a through hole in the valve body is in fluidic contact with the inlet and associated with the valve rod second chamber via a Bore with the drain is in fluidic contact.
  • the valve rod is arranged and designed such that via an actuation of the valve rod, the passage opening between the first and second chamber to open and close.
  • the valve body is guided under spring tension in the housing.
  • a return of the valve body is ensured in a simple manner.
  • the passage opening has a larger diameter than the through hole.
  • valve rod is guided biased by a spring element in the closed housing.
  • the actuating device is preceded by a main valve.
  • the main valve comprises a base and additional housing, wherein the base housing has an inlet and a drain and a valve seat arranged between inlet and outlet and the additional housing has a valve body operatively engageable valve body and a compensation chamber having an outlet opening.
  • the valve body is partially guided under spring preload in the additional housing and the compensation chamber is in fluid contact with the inlet of the main valve via a through hole in the valve body.
  • Acting as a pilot stage actuating device is in fluid contact with its inlet to the outlet opening of the main valve and its outlet with the flow of the main valve.
  • the through hole in the valve body of the actuator and the passage opening between the first and second chambers of the actuator has a smaller diameter than the through hole in the valve body of the main valve and the outlet opening of the compensation chamber of the main valve. Since the pressure in the inlet of the actuator is equal to the inlet pressure of the main valve, the actuator has the same performance as the main valve. Further, since the flow through the main valve is regulated and the cross sections have been selected accordingly, advantageously the actuating force which the device for actuating the valve stem of the actuator has to be applied is significantly lower.
  • Fig. 1 shows more or less schematically a generally designated by the reference numeral 10 actuating device for controlling a valve 10 flowing through the fluid.
  • the actuator 10 includes a base housing 12a with an inlet 14 and a drain 16. Between inlet 14 and outlet 16, a valve seat 18 is arranged.
  • the actuator 10 includes a valve body 20, which in turn is connected to a valve rod 22. About a lifting movement of the valve rod 22, the flow between the valve body 20 and valve seat 18 is controllable. The corresponding device for actuating the valve rod 22 will be described later.

  • the additional housing 12b fluid-tightly arranged on the base housing 12a, that the basic and additional housing 12a, 12b with the exception of the inlet and outlet 14, 16 a closed on all sides, fully enclosed, only a peripheral seal 24 having housing 12th form.
  • the additional housing 12 b is also designed such that the valve rod 22 is completely arranged without implementation completely inside the closed housing 12.
  • the already-mentioned device for actuating the valve rod in the present case comprises a magnet 26 fixedly connected to the valve rod 22 and an outer magnet 28 arranged outside the housing 12, which in turn is arranged displaceably via a frame element 30 to the housing 12.
  • the valve rod 22 is fixedly connected to an iron body 32 according to the second embodiment, so that in turn by a movement of the frame 30 with respect to the housing 12, a non-contact movement of the valve rod 22 is possible.
  • the additional housing 12b formed such that the valve rod 22 is completely and the valve body 20 partially guided in the additional housing 12b.
  • the valve rod 22 via a spring 34 and the valve body 20 are guided via a spring 36 under spring bias in the auxiliary housing 12b.
  • a first chamber 38 and a second chamber 40 are formed, which are in fluid communication with each other via a passage opening 42. While the first chamber 38 is in fluidic contact with the inlet 14 via a through bore 44 introduced into the valve body 20, the second chamber 40 is in fluidic contact with the drain 16 via a bore 46.
  • valve rod 22 is arranged and designed such that via an actuation of the valve rod 22, the passage opening 42 between the first and second chambers 38, 40 to open and close.
  • the force required to actuate the valve rod 22 is reduced:
  • the fluid is passed through the passage bore 44 in the valve body 20 into the first chamber 38 and thus onto the rear side of the valve body 20.
  • the valve body 20 is free of forces.
  • the valve body 22 with the full force of the spring 36 in the Valve seat 18 pressed.
  • a movement of the valve body 20 can now be achieved that the pressure acting on the top of the valve body 20 pressure is reduced.
  • the passage opening 42 between the first and second chambers 38, 40 is opened by a movement of the valve rod 22, so that fluid from the first chamber 38 via the passage opening 42 in the second chamber 40 and from there via the bore 46 to the drain 16 can flow.
  • the ratio of the passage opening 42 to the through hole 44 is selected so that the passage opening 42 allows a much larger flow, so that with complete opening of the passage opening 42 an almost complete reduction of the pressure above the valve body 20 can be achieved.
  • FIG. 3 illustrated third embodiment of the invention substantially corresponds to in Fig. 2 illustrated second embodiment. Unlike the in Fig. 2 shown second embodiment, only the device for actuating the valve rod is formed differently in the third embodiment.
  • valve rod 22 is in turn fixedly connected to an iron core 32 or an inner magnet 26. Outside the housing 12, a solenoid 48 is fixedly connected to the housing. By changing the current flow, a different force is exerted on the valve rod 22 by the electromagnet 48.

  • the additional housing 112b has a compensation chamber 138 with an outlet opening 142.
  • the outlet opening 142 is connected via a line 200 to the inlet 14 of the actuator 10 and the outlet 16 of the actuator 10 via a line 202 connected to the outlet 116 of the main valve 100.
